Potential for Marine Aquaculture

Consumption of seafood is expected to replace a considerable amount of meaty products in the future. Could widespread marine aquaculture in (open) coastal areas help in satisfying the global demand for seafood? Researchers from the University of California certainly think so. Using certain criteria they calculated that marine aquaculture could potentially produce 16.5 billions tons of fish per year or 4000 pounds per person! The question remains, however, where will the increased fish feed come from. Will high-protein vegetable crops be needed which production is based on land? Also, wild specimens need to caught in order to start a population of fish for breeding. Finally, care needs to taken on the implementation of marine aquaculture in coastal areas. Shrimp farms in South-East Asia have destroyed many coastal mangrove forests and discharged harmful contaminants in estuaries. Space is not necessarily an issue for marine aquaculture, it is more of applying it in a sustainable manner by rectifying the above challenges!
